My L5740 would not start because the battery was dead because a switch to an attachment was left on...or so I thought.
When I went to hook up my jumper cables so I could unload it off my trailer, the positive cable was loose. However, even after hooking up the jumper cables, I could not get ANY power in the cab.
I expected to get at least some power when I hooked the jumper to the positive terminal. What am I missing? Is there a fuse or relay that could be preventing all power beyond the battery?

If the positive cable was loose there could be corrosion between the cable end and the battery terminal. Begin the troubleshooting process with a fully charged battery. Remove cables from battery then clean battery terminals and cable ends. Replace cables on battery, tightening securely. If you can move it it's not secure. Follow ground lead to frame. Clean and tighten. Check your system now. This is the point from which to begin troubleshooting.

To troubleshoot starting and charging system issues yourself, get a multimeter and get familiar with using it

Even with tight, clean connections, if the battery is completely dead or shorted you won't get power immediately. I'd pull the battery, put it on a charger overnight, clean the terminals and re-install. But keep in mind, when a battery gets drained all the way, it severely diminished its life.

That's right. A good battery alone won't always have enough power to start the tractor if a completely dead battery is in the circuit.
Either get some charge into the dead battery or take it out of the circuit.

Thanks for the suggestions. I didn't have time to work on it today, and will try some of the suggestions tomorrow. The tractor is still on my trailer. It rained today, so I didn't need it.

On my L3130, it has a strap style battery post clamp, on the side opposite the side with the crimped on wire going to the starter there is a spade connector going to a small fuse box next to the battery that feeds the glow plugs, alternator and the dash. Have had problems with the terminal loosing connection with no start, glow plug and other issues and have had to rework it more than once. Check and see if that is a problem.

No luck so far. We have cleaned all connections at the battery and checked all fuses in the cab and still no power to the dashboard. I called my dealer and talked to a mechanic and he said to check under the dash for rat problems. I'll try that next.

You haven't indicated if you've tested the battery. If it's good, go to the main fuse and see if there's 12v coming in and going out. If there is go to the fuse box and see of there is 12v on the buss. If there is, find a fuse that has 12v coming out and try the devices on that circuit.

I don't think he has a meter
